X-Ray for PCBA

Automatic X-ray inspection utilizes the differences in different substances in X-ray absorption to inspect the parts and defects by checking 1%-2%. Mainly used to inspect defects such as extremely fine spacing, extremely high density circuit boards, bridges, missing parts, and poor alignment during the assembly process. It can also use its tomography technology to detect internal defects in IC chips. This is the only way to detect the quality of the ball grid array and solder ball welding.

Key Factors in PCBA Processing

There are several key factors that need to be noted during the PCBA processing:

1. Equipment accuracy: High precision SMT and welding equipment are the foundation for ensuring product quality. PCBA-TECH adopts advanced equipment to ensure the accuracy and stability of every step.

2. Raw material quality: High quality circuit boards and electronic components are a prerequisite for manufacturing high-performance products. PCBA-TECH strictly screens suppliers to ensure the high quality of raw materials.

3. Process control: A sound process and quality control system are key to ensuring product consistency and reliability.

PCBA-TECH has rich experience and professional knowledge, able to accurately control every process step.

Function Test

In order to verify the pcba quality,function test is necessary.

You can provide firmware, software,programming and testing procedure to us,we have computer for testing and help you make the test fixture or tool.

FCT for PCBA

FCT(Functional Circuit Test) requires IC programming, simulation testing of the entire PCBA board’s functionality, identification of hardware and software issues, and provision of necessary SMT production fixtures and testing jigs.

AOI for PCBA

AOI is a type of testing equipment, also known as AOI optical automatic testing equipment, which has become an important testing tool and process quality control tool for ensuring product quality in the electronic manufacturing industry.

The working principle of AOI detection equipment is that during the automatic detection process, the AOI detection equipment machine automatically scans the PCBA product through a high-definition CCD camera, collects images, compares the test points with qualified parameters in the database, and after image processing, checks the solder joint defects on the target PCBA, and displays or automatically marks the defects.
